The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Mushrooms
Form the main body of the dish and soften into a tender filling as they stew.
Butter
Carries the mushrooms as they stew and adds richness, and fries the bread golden.
All-purpose flour
Thickens the buttery juices with the white roux to give the mushrooms body.
White roux
Added to moisten and thicken the mushrooms into a spoonable filling.

The step that matters

Stew until the butter is absorbed. Stewing gently lets the mushrooms release and reabsorb their liquid so they turn tender rather than watery or dry. Stopping too early leaves the filling wet, and cooking too hard can toughen or scorch it.

Swap the white pepper

How well each one fits the dish's main ingredients (mushroom, butter, flour, mace, lemon, bread):

  1. Nutmegfits better
  2. Marjoramfits better
  3. Thymefits better
  4. White pepperthe original

Fit is the average pairing score against mushroom, butter, flour, mace, lemon, bread. Candidates are from the same food group and used in at least 100 recipes.
